Adds support of NURBS weights or "rat bspline" in OBJ terms. Tries to guess Blender knot mode better: - Detects and closes loops. This decision is based on geometry only. No metadata is provided in OBJ for this, so importer has checkbox to disable this feature. - Bezier knot mode allows to import circles and circular arcs.
